Energy is essential entity for human being like food, air, and water. However, today energy has been challenged by the lack of supply and the growing demand. Further serious problem of energy is the strong dependence of supply on non-renewable sources that generate tons of CO2 causing unexpected climate change. Energy storage can help us to address these challenges because it can store energy for a later use and convert energy to be a better quality. By utilizing these functions, energy storage can make renewable sources more reliable and easier to use leading to the increase of supply. Furthermore, energy storage enables vehicles to utilize the electricity instead of oil through the burgeoning electric vehicles’ technology. Among other energy storage technologies, lithium ion batteries are very attractive because they cover a wide range of energy spectra and have high energy density. The development of lithium ion batteries is crucial task for addressing energy challenges. In this talk, I will focus on the development of cathode material, which is a key component for the performance of lithium ion batteries. In the advent of new applications such as plug-in electric vehicles (PHEV) or electric vehicles (EV), a lot of attention has gone to LiFePO4 because of its excellent safety and its inexpensive cost. However, LiFePO4 suffers from poor power capability which is essential requirement in vehicles. I will discuss what factors affect power density and how to improve it in LiFePO4. Through these understandings simple approach had been developed. With this approach LiFePO4 shows very high power capability. Developing materials brings up new possibilities such as the electrification of vehicles in lithium ion batteries which really help to address energy challenges.
